Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a locking mechanism for adjustable interval fork can be used to the relative position between fixed spacing adjustable fork and the fork bracing piece to further fix the axial interval of fork.
Referring to fig. 1-2, fig. 1 is a three-dimensional structural diagram of a locking mechanism for a fork with an adjustable spacing applied to a fork mechanism according to an embodiment of the present invention; FIG. 2 is a cross-sectional view of the adjustable spacing fork locking mechanism of FIG. 1.
Usually whole fork mechanism is connected with fork truck through the mounting panel 1 of vertical setting, and mounting panel 2 is established to the 1 upper end of mounting panel projection, runs through being provided with fork bracing piece 6 in mounting panel 2, and fork 4 sets up respectively in the both ends of fork bracing piece 6 and both can relative horizontal slip meet mutually, and this kind of manual realization of slip accessible also can realize through setting up other machinery or electronic parts, and this is not the utility model point of this case, therefore this paper is no longer repeated.
To ensure the balanced forces on the fork support bar 6, the mounting seat 2 is usually located at the center of the fork support bar 6. When the left and right forks of the fork 4 are respectively positioned at the outer end portions of the fork support rods 6, the axial distance of the fork 4 is the largest.
In a specific embodiment, the utility model provides an adjustable interval locking mechanism for fork, it sets up in the slider 5 of fork 4 and 6 junctions of fork bracing piece, is provided with the spout that can hold fork bracing piece 6 in the slider 5, the spout top is provided with vertical spacing groove 501, the spout is linked together with spacing groove 501, and spacing groove 501's cross sectional shape dovetail or T shape. A locking block 9 is arranged in the limiting groove 501, a cavity is arranged between the locking block 9 and the bottom of the limiting groove 501, a reset spring 16 and an electromagnet 20 are arranged in the cavity, and the up-down expansion of the locking block 9 is controlled by the reset spring 16 and the electromagnet 20.
In order to achieve a uniform force on the locking piece 9, the electromagnet 20 and the return spring 16 are usually arranged centrally above the locking piece 9, for example the electromagnet 20 is arranged in the return spring 16. The return spring 16 is preferably made of a non-magnetically conductive metal material. Of course, the number of the return spring 16 and the electromagnet 20 may be set to several.
In addition, a locking rack 7 capable of being matched with the locking block 9 is arranged on the pallet fork supporting rod 6, the locking rack 7 can be arranged on the upper surface of the pallet fork supporting rod 6 and extends along the axial direction of the pallet fork supporting rod, and usually, meshing teeth matched with each other can be arranged on the upper surface of the locking rack 7 and the lower surface of the locking block 9.
After the adjustment of the distance between the fork 4 at each time is finished, the position of the fork is fixed again by the aid of the locking mechanism, and further the situation that the fork is unstable due to the fact that the axial distance of the fork is changed in the process of transporting the goods when the goods are too large is avoided.
In particular, the electromagnet 20 may be controlled by an external control circuit, which may be provided on the fork support bar 6 or on the mounting base 2, which control circuit typically comprises a switch and the electromagnet 20 in series.
When the electromagnet 20 is electrified, the electromagnet attracts the locking block 9 to retract, at the moment, the locking state is released, and the pallet fork 4 can axially move relative to the support rod 6; when the electromagnet 20 is powered off, under the reset force of the reset spring 16, the locking block 9 extends out to be matched with the locking rack 7 for locking, and at the moment, the pallet fork 4 is fixed on the supporting rod 6.
Above-mentioned locking mechanism's locking mode accuracy is high, can the position of accurate fixed fork 4, and controls locking piece 9 degree of automation height through electro-magnet 20, can realize the locking or the unblock of fork 4 through the switch, and is very convenient quick.
Further, in order to avoid the failure of the electromagnet 20 or the power failure, a manual locking member may be added to the locking mechanism.
Specifically, a guide pull rod 18 connected with the locking block 9 through threads is arranged above the locking block, the lower end of the guide pull rod 18 is arranged into a thread section, a thread groove is formed in the upper end of the locking block 9, and the locking block 9 is detachably connected with the guide pull rod 18 through threads. The guide pull rod 18 is vertically arranged and penetrates through the outer side of the sliding block 5, and the sliding block 5 is provided with a yielding hole for the guide pull rod 18 to penetrate through. When the pallet fork 4 needs to be fixed, the guide pull rod 18 is pressed downwards to enable the locking block 9 to be meshed with the locking rack 7, and meanwhile, when the fixation needs to be released, the guide pull rod 18 is lifted upwards. The guide rods 18 are typically made of a non-magnetically conductive metal material to avoid interference with the electromagnets 20.
The upper end of the guide pull rod 18 can be provided with a pull ring 19, so that the operation is convenient. The guide pull rod 18 facilitates on the one hand the pulling up of the locking block 9 and on the other hand provides a guiding function for the longitudinal extension of the locking block 9.
On the basis of the arrangement of the guide pull rod 18, in order to further ensure the locking effect of the locking block 9, two return springs 16 can be arranged and symmetrically arranged on two sides of the guide pull rod 18, and the electromagnet 20 is sleeved on the outer side of the guide pull rod 18. In this way, the force applied to the locking block 9 is more balanced.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
It is right above the utility model provides an adjustable interval locking mechanism for fork has carried out detailed introduction. The principles and embodiments of the present invention have been explained herein using specific examples, and the above descriptions of the embodiments are only used to help understand the method and its core ideas of the present invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.
